Fine, but the term race has not always been used, nor as it maintained its
orginal meaning. Take a look at Hegel, Herder, Von Ranke, all three of
these people talk about the German race. Hmmm, so just over 100 years ago
the term race was used to describe what today we would proably call a
nation state. The concept of race developed within a specfic social
context and I do not think it is helpful to attempt to reduce the concept
through biological determinism. It fact, one might argue, it only muddies
the waters.
